How Does Climate Change Affect Sharks?

Climate change has had a major impact on the world’s oceans and the creatures that inhabit them. Sharks, in particular, are highly vulnerable to the effects of climate change. As temperatures rise, sharks’ habitats are becoming increasingly inhospitable, resulting in major population declines in some species.

Changes in Ocean Temperature

The main way that climate change is impacting sharks is through changes in ocean temperature. As the planet’s climate warms, ocean temperatures are rising, making some areas too warm for sharks to survive. This is particularly true of tropical species, which are adapted to living in warm, shallow waters.

Changes in Ocean Chemistry

Climate change is also affecting ocean chemistry, which can have a major impact on sharks. As the oceans become more acidic, it becomes harder for sharks to absorb oxygen, which can lead to population declines. Additionally, increased acidity affects the availability of food sources, meaning that some species of sharks may be unable to find enough food to survive.

Changes in Migration Patterns

Sharks are highly migratory creatures, and climate change is affecting their ability to move between different areas. Warmer waters mean that some sharks are forced to migrate further north or south in search of cooler waters. This can be difficult for species that have specific habitat requirements, as they may find it hard to adapt to new environments.


Climate change is having a major impact on sharks and their habitats. Warmer waters, changes in ocean chemistry, and shifts in migration patterns are all making it harder for sharks to survive. If we want to protect these creatures, it is essential that we act quickly to reduce the effects of climate change.
